Hi @Christopher, welcome to the forum ![]()
I have not experienced that issue before, but from your traceback:
- The error you’re getting is that 
collectionshas noMutableSequence, which is a class that was removed in Python 3.3, so is presumably trying to run Python 2.7 code with a more recent Python 3 version - It seems a bit odd that you’re running from inside your Downloads folder - did you get the code via git, or did you use some other approach?
 
I expect the issue here is some missing or incorrect setup. If it’s helpful the Linux instructions are provided as direct steps here ![]()
If that doesn’t work, please specify which Linux version you’re using, and any error messages you receive in the code fetching / compilation processes.
